PlCKET-BARBING 'MACHINE.

SPECIFICATION forming part of Iletters Patent No. 507,687, dated October 31, 1893.

Application filed April 14, 1893- Serial No. 470,862- (No model.)

'10 all whom it may concern:

Be it known that I, NATHAN A. PAINE, a citizen of the United States, residing at Cedar Falls, in the county of Black Hawk and State of Iowa, have invented a new and useful Barbing-Machine, of which the following is a specification.

The objects of this invention are to produce amachine adapted to receive fence-rails; automatically feed the same therethrough, moving them at intervals and adapting it to cut and form barbs, and drive the same into one or both edges of the rails thus fed, the barbs being set at regular and predetermined intervals along the edges of the rails, whereby the latter may be employed in the construction of barbed fences.

With these and variousother objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in theclaims.

' Referring to the drawing:-Figure 1 is a perspective view of a rail-barbing machine embodying my invention. tudinal sectional view. Fig. 3 is a transverse sectional view through the front portion thereof. Fig. 4 is a detail in side elevation of the lower end of one of the standards. Fig. 5 is a front elevation and bottom view of one of the chisels or cutters. Fig. 6 is a detail in side elevation and partial section of one of the barb'inserting arms and its lever.

Like numerals'of reference indicate like parts in all the figures of the drawings.

In practicing my invention I employ a suitable rear support, in this instance in the shape of a carpenters or joiners horse, the same being indicated as 1, and in front of the horse locate a rectangular frame 2, the same having its opposite ends provided with slots 3, pivoted in the lower ends of which are Vibratory levers 4:. Bands 5 encircle the upper corners of the frame and limit the outward movements of the vibratory levers, which outward movements are caused by an interposed curved spring 6 secured to the base of the frame and at its terminals bear ing against the levers. The upper ends of the levers are bifurcated, and pivoted upon bolts 7 are curved arms 8, the upper ends of the armsbeing outwardly disposed as shown (see Fig. 3). Above the pivots of the arms Fig. 2 is a longi- I bolts 9 pass through curved slots 10 formed in the arms, said bolts extending through the bifurcations and serving to limit the pivotal movements of the arms upon the levers. The lower ends of the arms are curved at their outer corners or rounded, as indicated at 12, and designed at their inner corners to bind upon the upper ends of the levers to which they are pivoted when said arms are thrown inward. The levers have their upper outer corners provided with extensions 13, and the same are perforated or provided with eyes 14 designed to receive the stock-wires from which the barbs are produced and upon which the cam or curved ends of the arms will bind when the upper ends thereof are forced inward, all for a purpose hereinafter apparent.

Supported upon the front and rear supports is a pair of side sills 15, the same being longitudinally disposed and arranged parallel, and said side sills are spaced apart and have their upper inner corners formed with ways 16 and their inner faces with loose frictional rollers 17 whose peripheries travel in the same plane with the ways.

Supported upon the sills 15 between the levers heretofore described. These bars have their inner faces adjacent to their ends provided with recesses 22, and axially journaled' therein are loose frictional rolls 23 which travel against the outer edges of the cam- -levers and serve to throw the sameinward ICO Upon the front ends of the sills an inverted U-shaped standard 29 is secured, and from the same depends a V-shaped spring 30 to the lower end of which is attached a link or clip 31. This link or clip 31 loosely receives and supportsa thrust-rod 32 whose rear end is secured to a push-bar 33. The front end of the push-bar is loosely connected to a block or head 34, whose under side is provided with teeth as shown. The rear end of the push-bar is pivoted by a pin 35 to a depending link or head 36, the link or head being bifurcated to receive the rear end of the push-bar and provided with a series of perforations 37 as is also the push-bar, whereby as will be obvious by removing the pin and reinserting the same in the various perforations various adjustments may be secured. An extension 38 rises from each of the standards in which the shaft 19 is journaled, and are connected at their upper ends by a crosspiece 39, from the center of which a pair of coiled springs 40 depend, the same having their lower ends connected to the link or head 36, whereby said link or head and the rear end of the push-bar, when not otherwise influenced, are elevated.

In rear of the standard 29 there is securely bolted to the opposite sills a pair of vertical standards 41, the same being connected by a cross-head 42 at their upper ends, the ends of the cross-head extending beyond the standards and perforated in Vertical alignment with corresponding perforations formed in the front support of the machine. Vertically threaded rods 43 pass through these perforations and are nutted above the cross-head, said rods extending some distance beyond their nuts. Inner threaded rods 44 rise from the cross-head at the inner sides of the standards, and these pairs of rods receive crosspieces 45 above and below which nuts 46 are applied to the said rods, whereby the crosspieces may be raised and lowered and held in any of their adjusted positions.

Bearing-ears 47 rise from each of the cross pieces 45 and in the same is pivoted as at 48 a pair of levers 49. These levers converge toward their rear ends and are rigidly secu red to each other and to the upper end of the link or head 36 and are arranged directly under the loose rolls connecting the cross-arms of the main shaft, whereby, being in the path of said rolls or rollers they are struck and de pressed by each roller successively as it passes thereover, to be immediately re-elevated by the coiled springs 40 after said rolls have passed over the levers.

The standards 41 are provided at their lower ends with horizontal recesses 50 and in the same pairs of steel cutting'plates 51 are mounted for movement, said movement being secured through the medium of pairs of adjustingbolts 53 which extend through the front walls of the recess and are loosely connected to the cutting-plates. At the rear side reciprocating chisel 54, the same having a lower diagonal cutting edge adapted to operate against the cutting-plate. The upper end of the chisel has pivoted thereto as at 55 a pair of links 56 which in turn are pivoted at their upper ends as at 57 to the converging levers that are operated upon by the loose rollers 28 of the shaft 19.

A pair of springarms 58 is secured to the sills 15 in rear of the standards 41, and journaled as at 59 in said spring-arms immediately in rear of the standards and extending transverse the sills is a roller 60. A pair of inwardly disposed checking-arms 61 is located upon the sills 15 between the standards 29 and the standards 41 and are employed to prevent the possibility of the board or rail moving back ward, when the feed-devices move over the board to re-engage therewith for the purpose of subsequently drawing the board into the machine. These checking-arms are formed of spring-metal secured at their outer ends to the frame-work of the machine at each side of the way or feed-opening and are normally pressed into the path of the board so that the presence of the board causes them to spread. They are inclined in the same direction as the movement of the board when being fed into the machine, and hence resist, in a manner heretofore described, any backward movement of said board.

In preparing the machine for operation the leading ends of two wire strands of sufl'icient gage are first passed through the perforations in the vibratory levers and extended beyond the same under the cam levers and underthe chisels to the inner sides of the standards 41. The machineis now operated so thatthechisels are given a vertical reciprocation, and as they descend their edges being diagonally disposed produce a diagonal out upon the ends of the wires so that the leading ends of the wires are beveled or pointed. The board or rail to which the barbs are to be applied is now slid into the front end of the machine on the loose frictional rollers 17 and ways and under the spring-pressed roller 60, the latter serving to maintain the board or rail upon the ways and in direct transverse alignment with the leading ends of the wires and hence opposite the recesses in the standards 41. As the machine continues its movement the ends of the arms 21 are brought against the outer sides of the cam levers causing them to move a sufficient distance inward to first clamp or bind at their lower cam ends upon the wires, and continuing their movements the said arms are squeezed together or pressed inward so that the beveled ends of the wires are forced into the edges of the rail or board. \Vhen this has been accomplished the cam arms are from under the influence of their opcrating bars or arms 21 and are swung outward by the spring 6 in the lower front support of the frame. As they swing outward they release their bite upon the wires and move outward over the same. Immediately thereafter the chisels descend and again form a beveled vor diagonal cut upon each wire, thus producing the barb. Following this the push-bar passes over the board or rail which is prevented from moving backward by the said push-bar having forced its head a certain distance over the board or rail now retracts said head, and the latter having teeth on its under side engages with the board or rail and draws the same to the rear to the same extent that the push bar is operated or drawn. By this time the opposite ends of the arms 21 have arrived against the cam levers and the operation is repeated. The result of the operation is that the board or rail is fed out from the opposite end of the machine havinga uniformly disposed and regularly spaced apart series of beveled barbs at opposite sides thereof. 7

The spring 30 serves to lift the advanced end of the push-bar, when it is not otherwise influenced, so as to cause the same to readily ride over the rail or bar when said bar is moving to the front for a re-engagement with the rail or board and therefore not actuated or influenced by said rail or board; and on the other hand permits the head of the bar to become depressed by the mechanism before described into engagement with the bar or rail so that when said bar moves to the rear the board is drawn into the machine the length of the movement of the push-bar. By regulating the point of connection between the push-bar and the link or head 36 the movement of the bar may be regulated, and thus the barbs be set at different distances apart.

Various changes in the details of construction of my invention will readily suggest themselves to persons conversant with this class of machines, and I therefore do not limit my invention to such details as are herein shown and described, but hold that I may vary the same to any degree and extent within the knowledge of the skilled mechanic.
